Developing quasi-solid-state electrolytes (QSSEs) with excellent electrochemical stability at high voltage can improve the properties of the SDIBs, said a recent paper published in the journal of Advanced Functional Materials.
The researchers from the Shenzhen Institutes of Advanced Technology of the CAS developed a flexible SDIB based on a QSSE, which exhibits a porous 3D structure with apparently enhanced ionic conductivity, facilitating fast ionic migration of both anions and cations.
The SDIB showed excellent cycling stability with a capacity retention of more than 90 percent after 600 cycles, high flexibility and a wide working temperature range from minus 20 degrees Celsius to 70 degrees Celsius, said the paper.
The results suggested the potential of the batteries for high-performance flexible energy storage applications. (Xinhua)
Researchers from University of Science and Technology of China developed Cu catalyst composed of sharp needles which possesses high level of hydrophobicity and stability.
Recently, a research team from Qingdao Institute of Bioenergy and Bioprocess Technology exploited a new type of organic magnesium borate based electrolyte which was synthesized via a facile in-situ reaction of tris(hexafluoroisopropyl)borate [B(HFP)3], MgCl2 and Mg powders in 1,2-dimethoxyethane (DME).
